If you can’t find your library card, or aren’t sure if your account is still active, please email firstname.lastname@example.org. Our staff can verify the status of your account and get you your barcode number.
A PIN/password is required to login and manage your account and access digital content from home. Instructions for setting up a PIN or resetting your PIN can be found online.
Please note: Resetting your PIN will send an email to the address in your library record. If you no longer have access to that address, please email email@example.com for assistance.
Children and adults may both use our online forms to sign up for library cards. Please see "How do I get a Library Card?" FAQ for links to our applications.
Processing new cards requires a little work on our end. During normal business hours we are able to process most cards within an hour. If you've signed up for your card after 5 pm or on a weekend, it might take a little longer. Please email firstname.lastname@example.org with your name and barcode number and we will get back to you as soon as possible with the status of your account.
Some resources, including hoopla, Kanopy, and LinkedIn Learning, need to be signed up for using your specific home library. If you live in unincorporated Mill Valley, you may need to specify a different library. Check your home library here.
